Although we probably can't be terribly certain about any specific solution until later on Tuesday into Wednesday, the large-scale pattern looks favorable for this to actually stay put over the SE US & not trend terribly far northward as usual with the ridge over the southern Rockies and into west Texas. That ridge will try to kick our system towards the south and east, obviously details are still unknown atm and this could still shoot way up into the lower OH valley and Apps...
Here's my first call map (if you want to call it that) lol. I worded everything carefully and did my best to include most potential solutions. Anywhere between the I-20 & I-70 corridors is still legitimately fair game, and the only area I feel even remotely confident is over the climatologically favored south-central Appalachians and far western piedmont of NC and south-central VA.
